用荧光光谱法研究了迎春花瓣细胞与尿素分子相互作用。迎春花瓣含有多种荧光活性物质,通过捣碎的机械作用也能诱导出新的分泌物质。这些荧光活性物质与尿素分子相互作用,实现尿素的叶片吸收和荧光物质的荧光猝灭。随着尿素浓度的增加,在10-8—10-6m ol/L存在一个尿素诱导浓度区,在该浓度区内,尿素能够诱导出更多的细胞分泌物质,增加对尿素的吸收能力,此结果为植物生理,植物与生物小分子相互作用的研究提供重要信息。
Fluorescence spectroscopy was used to study the interaction between petals of spring petals and urea. Spring petals contain a variety of fluorescent active substances, through the mashed mechanical effects can also induce new secretions. These fluorescent active substances interact with urea molecules to achieve the absorption of urea and the fluorescence quenching of fluorescent substances. With the increase of urea concentration, there is a urea-induced concentration region at 10-8-10-6 m ol / L. In this concentration region, urea can induce more cellular secretion substances and increase the absorption capacity of urea. The results provide important information for the study of plant physiology and the interaction of plants with biological small molecules.
